The COOKIES module protects users from executing JavaScript code provided by third parties, e.g., to display ads or track user data without consent.
The cookies_asset_injector module (a sub-module of the COOKiES module) also allows inline JavaScript to be included in consent management. However, this does not adequately check whether the provided JavaScript code originates from authorized users.
A potential attacker would at least need permission to create and publish HTML (e.g. content or comments).
